Title: Improvements in or relating to arrangements for locating obstacles by electromagnetic waves
IPC: G01S7/282
Filed: 1945-05-25
Abstract: 618,499. Radiolocation; pulse circuits. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and HOUGHTON, L. W. May 25, 1945, No. 13201. Addition to 586,833. [Classes 40 (vi) and 40 (vii)] In a radiolocation system as described in the parent Specification, in which a pulse-generating saw-tooth oscillator is synchronized by the reflected pulses so that the pulse-recurrence frequency is a measure of the distance to the reflecting object, faulty operation by reflected pulses from objects beyond the range for which the system is designed, i.e. at distances greater than that corresponding to the maximum pulserecurrence frequency provided by the oscillator circuits, is prevented by biassing the grid of the oscillator, which is of the gas-filled type, by a potential obtained by rectifying the sawtooth output. In the system shown, the output of the gas-filled triode 11 is fed to a valve 23 which constitutes the first valve of the pulse generator and may be of the overload type. The storage condenser for the relaxation circuit comprises a condenser 15 fed through a resistance 16 and the time constant of the circuit for a given grid bias determines the maximum range of the system. A diode 28 with a load resistance 21 and storage condenser 29 is arranged across the tube 11, and the rectified output is applied to the range meter 9 and to the grid of the tube 11. The bias thus applied to tube 11 varies inversely with the anode potential so that it has a small value, which can be overcome by echo pulses, just before the tube is due to fire, but has a large value after the tube has fired so that echo pulses arriving from objects beyond the maximum range are unable, due to this bias and to their relatively-small amplitude, to fire it again.
Patent GB-132157-A (GB)
IPC: B21C37/06
Abstract: 132,157. Schneider et Cie. Oct. 14, 1918, [Convention date]. Ordnance. - In the manufacture of tubes. particularly for guns, by the self-hooping process, in which successive zones of the tube are subjected to different pressures by fluid in the annular space between the tube and an inner mandrel, the length of the zone treated is determined by tubular sections surrounding the mandrel, and removable one by one. These sections form an abutment fixing the positicn of a packing ring confining the fluid. In one form, the mandrel B, Fig. 1, extends through the tube A and is retained by nuts C, C', D. Tubular sections F<2>, F<3>, F<4>, F<5>, F<6> surround the mandrel and respectively correspond in length with the lengths of the zones Z<2>, Z<3>, Z<4>, Z<5>, Z<6> to be treated successively. The fluid under pressure, admitted to the annular space between the tube and mandrel through an opening b in the mandrel, is confined at one end by a packing ring behind the member D and at the other by a slidable packing bearing against the section F<6>. This packing, Fig. 3, comprises bevelled rings H, I, which may be split, and a rubber &c. ring G of channel form positively engaged by a barbed projection on a driving ring J. The packing is kept against the abutment F<6> by pressure of the fluid. When the zone Z<1> has been treated, the nut C<1> is removed and the fluid pressure is utilised to drive the packing and sections to the right, expelling the section F<2> and exposing the zone Z<2> to the fluid. The nut C<1> is replaced and the zone Z<2> treated. The remaining sections are similarly removed one by one. In another form, Fig. 4, the mandrel extends only through the part of the tube being treated, and carries the sliding packing. The sections F<2> &c. surround that part of the mandrel external to the tube and form an abutment for the nut C, determining the extent to which the mandrel enters the tube. The sections are preferably each in two parts connected by bolts and flanges to facilitate removal. As each section is removed, the mandrel is advanced a corresponding distance into the tube by the fluid pressure.

Filed: 1966-03-25
Abstract: 1,139,974. Photographic shutters. EASTMAN KODAK CO. March 25, 1966 [March 25, 1965], No. 13217/66. Heading G2A. A photographic camera comprises a shutter speed setting member (34) Fig. 7 (not shown) having a bulb position, detent means 90-94 for holding the setting member in the bulb position, a shutter trigger member 8, 10 coupled to the shutter to open the same on actuation of the trigger member, means 96 for arresting the shutter in the open position, which means are ineffective except in the bulb position of the setting member, and a coupling between the trigger member and the detent means to release the setting member to a setting other than bulb upon actuation of the trigger member. Setting the member (34) to the bulb position pivots, via the lug 94 engaging a disc 30, the lever 90 clockwise (as shown) so as to position the hook 96 in the path of a shutter actuating lever (52) Fig. 4 (not shown) and to tension a spring 88. Depression of the shutter release member 8 causes a toe (48) Fig. 4 (not shown) to disengage a latch (50) from the shutter actuating lever (52) which rotates anti-clockwise (Fig. 4) until it strikes the hook (96). In this position Fig. 6 (not shown), the heel (58) of the lever (52) has moved a lever (62) into a position holding the shutter blades (66) open. The blades remain open as long as shutter release member 8 remains in its lowermost position. Depression of the member 8 also turns a lever (104) Fig. 5. (not shown) clockwise, which in turn moves lever (90) further in a clockwise direction thereby withdrawing the lug (94) from engagement with the disc (30), which then with the member (34) runs down to its initial or 1/250th exposure position under action of the spring (88). When the member 8 is allowed to rise, the toe (48) (Fig. 4) engages the lever (52) and pivots the lever clockwise, the heel (58) thereof allowing the lever (62) to close the shutter blades (66). For a normal exposure Figs.1, 2 (not shown), the member (34) is set, thereby moving, via disc (30), a speed control pin (24) which is followed by an arm (22) of a time delay sector (18). Depressing the member (8) frees the lever (52) from the latch (50) and opens the shutter blades as before, but in this case the lever (52) continues to rotate anti-clockwise (Fig. 2). An arm (68) thereof contacts a pin (16) of the sector (18), which then moves in a clockwise direction, the movement thereof being slowed by teeth of a retard weight (40) meshing with teeth on the sector. The desired shutter delay is determined by the distance through which the sector (18) rotates prior to the arm (68) slipping off the pin (16). Then the heel (58) rides over the lug and the shutter blades are closed by an arm (70) of the lever (52) bearing against a lug (72) of the lever (62). As the member (8) rises, the toe (48) then engages the arm (68) to drive the lever (52) clockwise, the heel (58) riding over the lug (60) so that the shutter mechanism is reset.

Title: Improvements in or relating to moulding compositions containing phenol aldehyde resins
IPC: C08K3/22
Filed: 1943-08-17
Abstract: Moulding powders are obtained by mixing with a syrupy one-stage phenol-formaldehyde resin, obtained by reacting a phenol in the presence of a basic catalyst with all the methylene-containing compound necessary for heat-convertibility and by removing a substantial portion, but not all of the water and other volatile material from the reaction product to provide a syrupy resin at room temperature due to the presence of the residual water and volatile material, a relatively small amount of an alkali metal oxide or an alkaline earth oxide in a mixer, removing said mixture from the mixer and allowing the mixture to solidify and grinding it to a powder. The powder is then mixed with fillers, e.g. long-fibred asbestos, wood flour, cotton linters, fabric, mica slate dust and with hexamethylenetetramine or like methylene-containing compound as hardener; alternatively, the fillers may be added to the syrup. Resins having hydrophilic properties, e.g. those produced from phenol, m-cresol or mixtures of m- and p-cresol with phenol, are preferred; furfural or hexamethylene tetramine may be used instead of formaldehyde and a lubricant, e.g. calcium stearate, may be added, 100 pts. phenol and 80 pts. 40 per cent formaldehyde solution and 5 pts. concentrated ammonia solution are refluxed for 50 mins.  Excess water is removed by evaporating the resin in an open dish at 108 DEG C.  The resin containing about 25 per cent volatiles is mixed in a ball mill with 3-4 per cent magnesium oxide and 50 per cent asbestos, and after solidification is ground to a powder.
